云生态系统的能量感知负载均衡策略

Energy-aware Load Balancing Policies for the Cloud Ecosystem

Ashkan Paya, Dan C. Marinescu

摘要:

计算机和通信系统的能耗并不与工作量成线性比例。即使在空闲或轻负载时,系统也会使用大量的能量。一个广泛报道的大型数据中心资源管理解决方案是将负载集中在服务器的子集上,并尽可能将其余服务器切换到可能的睡眠状态之一。我们提出了一个传统的负载均衡的概念,旨在优化大规模系统的能源消耗:{ \it均匀地分配工作负载的最小的一组服务器运行在一个最佳的能源水平,同时遵守QoS约束,如响应时间。}我们的模型适用于集群系统,该模型还要求在每个重新分配间隔的系统资源的需求以有界的速度增加。在本文中,我们报告了应用程序扩展的VM迁移成本。

英文摘要:

The energy consumption of computer and communication systems does not scale linearly with the workload. A system uses a significant amount of energy even when idle or lightly loaded. A widely reported solution to resource management in large data centers is to concentrate the load on a subset of servers and, whenever possible, switch the rest of the servers to one of the possible sleep states. We propose a reformulation of the traditional concept of load balancing aiming to optimize the energy consumption of a large-scale system: {\it distribute the workload evenly to the smallest set of servers operating at an optimal energy level, while observing QoS constraints, such as the response time.} Our model applies to clustered systems; the model also requires that the demand for system resources to increase at a bounded rate in each reallocation interval. In this paper we report the VM migration costs for application scaling.
